Q. I am unable to connect to the Internet. How do I establish a connection?

The following is a checklist you should go through after failing to connect to the Internet.

1. Does a window asking for a username and password pop up more than once? If so, verify your username and password. First, you should check to make sure your CAPS LOCK is not on - this will cause you to type letters in capital, making your password incorrect (your password should be in lowercase). Second, be sure your username is typed in correctly. An incorrect username will result in the same error message. Next, be sure no spaces are in front or behind your username or password. If you are not sure, erase everything in each field and retype both entries.

2. Reboot your machine.

3. Check your Dial-up Network settings. Below you will find how to get to your dialer settings and how they should look.

For Windows 98 (Windows 2000 users will see a similar screen)

1. Double-click "My Computer." (Windows 2000 and Windows ME users will need to go to "Start," then "Settings," and then double-click on "Dial-Up Networking")

2. Double-click "Dial-Up Networking."

3. Right-click on your "My Connection" icon. (Note: you may have named it something else. For example, the name of your Internet Service Provider)

4. Go to "Properties."

5. Your dialer settings should match the figures below.

• Make sure the "TCP/IP" box is checked. See Figure 1.0
• Make sure the "Enable Software Compression" box is checked. See Figure 1.0
• Make sure the user is set to "Server assigned IP address." See Figure 1.1
  
• Make sure the user is set to "Server assigned name server addresses." See Figure 1.1
• Make sure the "Use default gateway on remote network" box is checked. See Figure 1.1
• If you are still having trouble connecting, you may want to un-check the "Use IP header compression" box. See Figure 1.1

4. Make sure the Microsoft VPN Adapter is not selected under "Connect using" in the General tab.

5. Windows NT? In the Security Tab in Phonebook, make sure that "accept any authentication including clear text" is checked.

6. Recreate the dialer.

1. Double-click "My Computer." (Windows 2000 and Windows ME users will need to go to "Start," then "Settings," and then double-click on "Dial-Up Networking")

2. Double-click "Dial-up Networking."

3. Double-click "Make New Connection," and follow the instructions.

7. Try disconnecting any phones, caller ID boxes, answering machines, line splitters from line. Plug modem directly into the line. Try using a different phone cord between modem and phone socket. Check for line noise.

8. Reinstall TCP/IP.

9. Reinstall all dial-up components.

10. Modem issue? Update modem drivers, try initials and commas, etc.

11. Try a different modem.

Q. Sometimes I get disconnected from my Internet service. What could be causing this?

A. Following are some common reasons for losing your connection.

Of course, there are several factors that can affect your connection outside your home as well, such as damaged lines, carrier devices, and even weather conditions. To determine if there are any outside factors at work, you will need to contact your phone provider. When calling to have your line checked, rather than telling them it is computer related, tell them that you are having problems being heard by and hearing the other party (the second you mention computers or Internet they will pass your problem off on us, as they are obligated only to provide voice grade service to customers - voice grade is all a modem needs to function though, so your end result is having them service the line to improve the quality to voice grade). Also, your phone provider may not catch the problem the first time through - don't be afraid to ask them to check it again if the problem persists, but be absolutely sure that you have explored the other reasons listed below - they can't fix it if it's not broken.

Q. Why do I only connect at 21600 or 24000 when I have a 28800 or 33600 modem?

A. Many factors affect how "fast" your modem connects:

• Your phone line conditions and distance from your phone company.
• Your modem make & configuration.
• Your PC's software configuration.
• Compatibility between your modem and ours.

Your modem may connect at a variety of different speeds depending on these factors. Many of our users are located in rural areas - expect mid to lower 20s from your 28.8 or 33.6 modem - modems in these types of areas just can't connect as fast because of the miles of telephone lines that they must "talk" over.

BACK TO TOP

Q. Why don't I connect any faster than 33.6 when I have a 56K modem?

A. More than likely you are experiencing one of the following:

• You live too far away from your phone company's central office.
• You have too much line noise or interference.
• You have more than one analog to digital conversion in your phone line.
• Do you have a V.90 or K56Flex modem? If not you will not connect above 33.6.

BACK TO TOP

Q. How can I improve my connect speed?

A. If your connection is excessively slow or frequently dropped, you may have some line noise problems. See the section above pertaining to line noise. You should always have the latest firmware for you modem - especially if you have a 56K modem. Firmware updates are done to fix common problems with modem connections. Failing to keep your firmware current is a major cause of "it used to work and now it doesn't" problems. ISPs upgrade their firmware on their communications servers very regularly to keep up with newer model modems - be sure your modem keeps up too. Contact your modem's manufacturer for more information. Or, you may simply need to configure your modem differently by using a modem initialization string, which is an easy thing to try! If you don't know anything about initialization strings, you can contact your modem's manufacturer for more information.

Q. If I have unlimited access, then why do I get kicked off if I have a connection that has been idle for 15 minutes?

A. It is considered abuse of service to remain connected and inactive for extended periods of time. Unlimited means use it when you need to - if that means 5 minutes per day or 5 hours per day - but does not mean you have a dedicated connection to the Internet to leave connected 24/7 whether you are using it or not. It is not fair to your ISP or your neighbors who want to use the Internet as well.

BACK TO TOP

Q. What is the definition of Unlimited Access?

A. We define Unlimited Access as accessing our services on an "as needed" basis when the user is actively participating in the session and sitting at the computer. When a user steps away from the computer for more than a few minutes, he or she should disconnect and reconnect later when necessary. We see it the same as making a phone call - when you are done talking to the other party, you hang up the phone and call back later when you want to talk again.

Q. How do I set up my e-mail account?

A. These instructions are intended to help customers configure Microsoft Outlook Express.

1. Open Microsoft Outlook Express.

2. Go to "Tools" on the menu bar, and then select "Accounts." You should see a window like the one below.

3. Make sure the "Mail " tab is selected. Go to the "Add" button , and then select "Mail."

4. In the Display name field, type in the name you would like to appear in your e-mail. Click Next.

5. Enter your e-mail address in the field provided. Click Next.

6. Make sure your incoming mail server is selected as a "POP3" mail server. In the Incoming mail (POP3, IMAP, or HTTP) and in the Outgoing mail (SMTP) server fields, type in, as an example, mail.yourdomain.com. Your domain name proceeds the @ symbol in your e-mail address. For example, if your e-mail address is username@smartwire.net, your Incoming and Outgoing mail would be mail.smartwire.net. Click Next.

7. Type your username in the "Account name" field, and your password in the "Password" field. Use the same username and password you used to sign-up, or use the most current username and password your Internet Service Provider has given you. Click Next.

8. Click Finish to save your settings.

BACK TO TOP

Q. How do I set up an additional e-mail?

A. Additional emails are setup the same way as default e-mail addresses (see above), except you would enter a different e-mail address (Step 5 above), and a different account name and password (Step 7). You may also choose to use a different display name (Step 4).

BACK TO TOP

Q. I can't send or receive e-mail. How do I get it to work?

A. There may be an error in your Outlook Express e-mail settings. Let's check, shall we?

1. Open Microsoft Outlook Express.

2. Go to "Tools" on the menu bar, and then select "Accounts."

3. In the Mail tab, go the e-mail account you are having trouble with and click on the "Properties" button.

4. Click on the General tab. You should see a screen similar to the one below. Make sure the "Include this account when receiving mail or synchronizing" box is checked. Also, make sure your correct e-mail address is typed in the E-mail address field. Click Apply.

5. Click on the Servers tab. Make sure your Incoming mail (POP3) and Outgoing mail (SMPT) server names are correct. For example, if your e-mail address is username@smartwire.net, then your Incoming and Outgoing mail server names would both be mail.smartwire.net. Also, make sure you have entered your correct username and password. You may want to reenter them just in case. Both the "Log on using Secure Password Authentication" and "My server requires authentication" boxes should be unchecked. Click Apply.

6. Click on the Connections tab. Make sure the "Always connect to this account using" box is unchecked.

7. Click on the Security tab. Your screen should look like the one below. Click Apply.

8. Click on the Advanced tab. Make sure both "This server requires a secure connection (SSL)" boxes are unchecked. Click Apply.

9. Click OK to save your settings.

• 600 An operation is pending.  This is probably due to a hung program running in the background. use CTRL+ALT+DEL to get the task manager, if there is anything listed with [Not Responding] end task it. If that doesn't sort it shut down everything that you don't need.  If this doesn't work, try restarting the computer.

• 601 An invalid port handle was detected.  First check what COM port the modem is installed on. This can be checked by going to Control Panel -> Modems. Click on Diagnostics and see what COM port the modem is installed on. Highlight that port and select "More Info." If there are no ports listed then send the user to the computer manufacturer to get their ports reinstalled.  If you get an address and a UART but no Ati responses, then there is either no modem on that COM port or it is not properly installed. If you get no address and no UART but you do get Ati responses then it is a WinModem, test it using HyperTerminal. If it works in HyperTerminal but not using DUN then reinstall the drivers (be careful, Winmodems often have several disks supplied by the manufacturer and/or have complicated installation procedures. If you are not comfortable with reinstalling a modem get the user's computer manufacturer to do it.)  Try using HyperTerminal to connect to all your COM ports one by one and see is there a modem installed on any of them by typing AT and seeing do you get an OK response.  If you get a modem response on a COM port, then try reinstalling the modem onto that COM port. If this has no effect refer the user to their computer manufacturer.
• 602 The specified port is already open.  This often happens when another program is using the modem. Disable all fax software.  If this does not work then shutdown and turn off the computer. This forces the port to close.  If it still gives this error try reinstalling the modem. (Be careful with WinModems as they have often a lot of extra disks).  If not, contact the manufacturer and get them to sort it out.
• 603 The caller's buffer is too small.  Make sure the FIFO buffers are turned on if the user has a 16550 UART. If the buffers are on, try juggling with their settings until the error goes away.  If this has no effect, then set the FIFO buffers to their default settings, lower their port speed to 9600 and work the port speed up one step at a time until the error repeats itself. Use the highest possible port speed that does not make this error occur.  If the error occurs at 9600bps then the modem is possibly damaged, refer the customer to their manufacturer.
• 604 Incorrect information was specified.   1. Retype username and password.  2. Delete and remake the dialer or dialup connection.
• 605 The port information cannot be set.  The Remote Access Phone Book file and the current Remote access configuration are probably inconsistent. If you have changed your communications equipment (such as your serial port or modem), be sure to reconfigure Remote access.  If the error persists, remove and recreate the affected Phone Book entry or, reinstall Remote Access Service. The Remote Access Phonebook (rasphone.pbk) Is in the SYSTEM32/RAS subdirectory of your windows NT directory.
• 606 The specified port is not connected.  First check what COM port the modem is installed on. This can be checked by going to Control Panel -> Modems. Click on Diagnostics and see what COM port the modem is installed on. Highlight that port and select "More Info." If there are no ports listed then send the user to the computer manufacturer to get their ports reinstalled.  If you get an address and a UART but no Ati responses, then there is either no modem on that COM port or it is not properly installed.

If this has no effect refer the user to their computer manufacturer.
• 607 An invalid event is detected.  An internal error occurred. Restart your computer to make sure that all recent configuration changes have taken effect.
• 608 A device was specified that does not exist.  First check that the modem is installed. Make sure that the driver installed matches the modem exactly (go to Modems in Control Panel, click Diagnostics, highlight the COM port your modem is listed as, click More Info. Your modem name as listed in Control panel -> Modems should match the one beside ati3) If not reinstall the modem (be careful of WinModems as they often have complicated installation procedures)  If the modem is installed correctly, check that it is responding properly. Go to Control Panel, then Modems. Click on the Diagnostics tab. Highlight the COM port the modem is on and then select More Info. If the modem does respond, check it further by dialing using HyperTerminal.  If the modem fails any of these tests, get the modem checked by the manufacturer. If the modem passed all of these tests, try reinstalling DUN/RAS.
• 609 The device type was specified that does not exist.  First check that the modem is installed. Make sure that the driver installed matches the modem exactly (go to Modems in Control Panel, click Diagnostics, highlight the COM port your modem is listed as, click More Info. Your modem name as listed in Control panel -> Modems should match the one beside ati3) If not reinstall the modem (be careful of WinModems as they often have complicated installation procedures)  If the modem is installed correctly, check that it is responding properly.

If the modem does respond, check it further by dialing using HyperTerminal.  If the modem fails any of these tests, get the modem checked by the manufacturer. If the modem passed all of these tests, try reinstalling DUN/RAS.
• 610 An invalid buffer was specified.  An internal error occurred. Restart your computer to make sure that all recent configuration changes have taken effect.
• 611 A route was specified that is not available.  Most likely, your network configuration is wrong. Restart your computer to make sure that all recent configuration changes have taken effect.  If error persists, tell the user to contact their system administrator.
• 612 A route was specified that is not allocated.  Your network configuration is probably incorrect. Restart your computer to make sure that all recent configuration changes have taken effect. This error may also occur if your computer is running low on resources. If the error persists, consult the Windows 2000 event log for detailed warnings or errors.
• 613 An invalid compression was specified.
• 614 There were insufficient buffers available.   Try adding &K0 to the modem's string. This will turn off compression.  If that doesn't work then it could be due to a modem incompatibility problem or an incorrect driver.
• 615 The specified port was not found.  First check what COM port the modem is installed on. This can be checked by going to Control Panel -> Modems. Click on Diagnostics and see what COM port the modem is installed on. Highlight that port and select "More Info." If there are no ports listed then send the user to the computer manufacturer to get their ports reinstalled.  If you get an address and a UART but no Ati responses, then there is either no modem on that COM port or it is not properly installed.

If this has no effect refer the user to their computer manufacturer.
• 616 An asynchronous request is pending.  An internal error (Windows operating system) has occurred. Microsoft advises to shut-down and re-start computer to make sure that all recent configuration changes have taken effect.  If this does not correct the problem, you may need to remove and re-install portions of Windows, or re-install Windows.
• 617 The modem is already disconnecting.  The modem is already disconnecting.  Wait for Network and Dial-up Connections to finish disconnecting.
• 618 The specified port is not open.  This often happens when another program is using the modem. Disable all fax software.  If this does not work then shutdown and turn off the computer. This forces the port to close properly.  If it still gives this error try reinstalling the modem. (Be careful with WinModems as they have often a lot of extra disks).  If not, contact the manufacturer and get them to sort it out.
• 619 The specified port is not connected.  This often happens when another program is using the modem. Disable all fax software.  If this does not work then shutdown and turn off the computer.

• 620 No endpoints could be determined.
• 621 The system could not open the phonebook.
• 622 The system could not load the phonebook.
• 623 The system could not find the phonebook entry for this connection.
• 624 The system could not update the phonebook file.
• 625 The system found invalid information in the phonebook.
• 626 A string could not be loaded.
• 627 A key could not be found.
• 628 The connection was closed.  This could be caused by several things.  If the user was cut off in the middle of a session it was most likely a line drop or a failure on the ISP's end. For dropped connections try
  S10=50
  S10=100
  S10=100S25=200

  For a problem on the ISP's end, which should only happen very infrequently, and reconnecting should usually solve it.  If the user was disconnected while trying to connect, chances are there is a setting wrong somewhere in the DUN connection, or in TCP/IP in the Network Control Panel. Make sure that all the settings are correct.  Check if the problem occurs every time they attempt to connect or only once. If it doesn't reoccur then chances are it was a glitch at our end.  If it occurs constantly and they have never successfully connected then it may be a modem problem. Try the following strings:
  AT&F1
  ATZ&B0&C1&D2

• 629 The connection was closed by the remote computer.  This could be caused by several things.  If the user was cut off in the middle of a session it was most likely a line drop or a failure on the ISP's end.  For dropped connections try
  S10=50
  S10=100
  S10=100S25=200

  For a problem on the ISP's end, which should only happen very infrequently, and reconnecting should usually solve it.  If the user was disconnected while trying to connect, chances are there is a setting wrong somewhere in the DUN connection, or in TCP/IP in the Network Control Panel.

If it doesn't reoccur then chances are it was a glitch at our end.  If it occurs constantly and they have never successfully connected then it may be a modem problem. Try the following strings:
  AT&F1
  ATZ&B0&C1&D2

• 630 The modem was disconnected due to hardware failure.  This error is most likely caused by the user's modem.  First check if the error occurs regularly or has only happened once.  If it only happened once then make sure the user's port speed is not set too high.  MAX Values:
  57600 for 56k modems
  38400 for 33.6k modems
  19200 for 14.4 modems

  If it happens regularly, check the port speed as above and then try these strings:
  AT&F1
  ATZ&B0&C1&D2

  If these have no effect then get the user to have their modem checked out by the manufacturer.

• 631 The user disconnected the modem.  The user disconnected themselves. There is no fix, just connect again.
• 632 An incorrect structure size was detected.
• 633 The modem is already in use or is not configured for dialing out.
• 634 Your computer could not be registered on the remote network.
• 635 There was an unknown error.  Get the user to try again, the error should go away or be replaced with a more descriptive one.  If the error persists the try reinstalling DUN/RAS. If it asks you do you want to keep a file answer NO just in case some of the newer files are corrupted.
• 636 The device attached to the port is not the one expected.
• 637 A string was detected that could not be converted.
• 638 The request has timed out.
• 639 No asynchronous net is available.
• 640 A error has occurred involving NetBIOS.  The user has a NetBIOS Network, check the DUN settings as best you can and then if that doesn't work get them to contact their LAN Administrator and make sure that their LAN is set up for external access.
• 641 The server cannot allocate NetBIOS resources needed to support the client.  The user has a NetBIOS Network, check the DUN settings as best you can and then if that doesn't work get them to contact their LAN Administrator and make sure that their LAN is set up for external access.
• 642 One of your computer's NetBIOS names is already registered on the remote network.  The user has a NetBIOS Network which is using a computer name which exists on the remote network. Check the DUN settings as best you can and then if that doesn't work get them to contact their LAN Administrator and make sure that their LAN is set up for external access.
• 643 A network adapter at the server failed.
• 644 You will not receive network message popups.
• 645 There was an internal authentication error.  This is a tricky one to pin down as it seems to be a catch all error.  First check all the DUN settings, make sure that they are exactly as they should be. Delete any extra DUN connections that the user doesn't use. Make sure that IE and OE are using the same DUN connection.  Try deleting *.pwl     If none of these work then try reinstalling DUN.
• 646 The account is not permitted to log on at this time of day.
• 647 The account is disabled.
• 648 The password for this account has expired.
• 649 The account does not have permission to dial in.
• 650 The remote access server is not responding.   This error can result from a missing or corrupted telephon.ini file. To resolve this follow the steps below.
  • From the Start menu select "Find", and then select "Files or Folders".
  • In the "Named" field type "telephon.ini" Look on the C:\ (usually)
  • If telephon.ini file is found, rename it to telephone.old.
  • From the "Start" menu select "Run", type "tapiini.exe"., and then click OK. (nothing will really seem to happen.)
  • Reboot, and retry the connection.

  If this doesn't fix it, it may be that you are trying to dial in using K56Flex or X2. Enable V.90 on X2 off or V.90 on K56Flex off depending on what your modem supports.

• 651 The modem has reported an error.  This error is most likely caused by the user's modem.  First make sure that the modem is connected to the phone lines correctly and if it is an external modem make sure that the serial cable is connected to the right COM port and that the cable is not tangled.  Then check if the error occurs regularly or has only happened once.  If it only happened once then make sure the user's port speed is not set too high.  MAX Values:
  57600 for 56k modems
  38400 for 33.6k modems
  19200 for 14.4 modems

  If it happens regularly, check the port speed as above and then try these strings:
  AT&F1
  ATZ&B0&C1&D2 

  If these have no effect then check that the modem is installed. Make sure that the driver installed matches the modem exactly. If not reinstall the modem (be careful of WinModems as they often have complicated installation procedures)  If the modem is installed correctly, check that it is responding properly. Go to Control Panel, then Modems. Click on the Diagnostics tab. Highlight the COM port the modem is on and then select More Info. If the modem does respond, check it further by dialing using HyperTerminal.

  If the modem fails any of these tests, get the modem checked by the manufacturer. If the modem passed all of these tests, try reinstalling DUN/RAS

• 652 There was an unrecognized response from the modem.  This error is most likely caused by the user's modem.  First make sure that the modem is connected to the phone lines correctly and if it is an external modem make sure that the serial cable is connected to the right COM port and that the cable is not tangled.  Then check if the error occurs regularly or has only happened once.  If it only happened once then make sure the user's port speed is not set too high.  MAX Values:
  57600 for 56k modems
  38400 for 33.6k modems
  19200 for 14.4 modems

  If it happens regularly, check the port speed as above and then try these strings:
  AT&F1
  ATZ&B0&C1&D2

  If these have no effect then check that the modem is installed. Make sure that the driver installed matches the modem exactly. If not reinstall the modem (be careful of WinModems as they often have complicated installation procedures)  If the modem is installed correctly, check that it is responding properly. Go to Control Panel, then Modems. Click on the Diagnostics tab. Highlight the COM port the modem is on and then select More Info. If the modem does respond, check it further by dialling using HyperTerminal. .  If the modem fails any of these tests, get the modem checked by the manufacturer.

  If it happens regularly, check the port speed as above and then try these strings:
  AT&F1
  ATZ&B0&C1&D2

  If these have no effect then check that the modem is installed. Make sure that the driver installed matches the modem exactly. If not reinstall the modem (be careful of WinModems as they often have complicated installation procedures)  If the modem is installed correctly, check that it is responding properly. Go to Control Panel, then Modems. Click on the Diagnostics tab. Highlight the COM port the modem is on and then select More Info. If the modem does respond, check it further by dialing using HyperTerminal.  If the modem fails any of these tests, get the modem checked by the manufacturer. If the modem passed all of these tests, try reinstalling DUN/RAS.

• 667 The system was unable to read the media .INI file.  The modem is probably not installed properly. Get the user to reinstall the modem and/or contact the manufacturer.
• 668 The connection was terminated.  This could be caused by several things.  If the user was cut off in the middle of a session it was most likely a line drop or a failure on the ISP's end.  For dropped connections try
  S10=50
  S10=100
  S10=100S25=200

  For a problem on the ISP's end, which should only happen very infrequently, and reconnecting should usually solve it.  If the user was disconnected while trying to connect, chances are there is a setting wrong somewhere in the DUN connection, or in TCP/IP in the Network Control Panel. Make sure that all the settings are correct.  Check if the problem occurs every time they attempt to connect or only once. If it doesn't reoccur then chances are it was a glitch at our end.  If it occurs constantly and they have never successfully connected then it may be a modem problem. Try the following strings:
  AT&F1
  ATZ&B0&C1&D2

• 669 The usage parameter in the media .INI file is invalid.
• 670 The system was unable to read the section name from the media .INI file.
• 671 The system was unable to read the device type from the media .INI file.
• 672 The system was unable to read the device name from the media .INI file.
• 673 The system was unable to read the usage from the media .INI file.
• 674 The system was unable to read the maximum connection BPS rate from the media .INI file.
• 675 The system was unable to read the maximum carrier connection speed from the media .INI file.
• 676 The phone line is busy.  The line is busy.  First check that the user is dialing the correct phone number. This error occurs if they are dialing their own number.  Check also that the modem is connected properly to the phone line. If the user has two sockets on the back of the modem then make sure that the line from the phone jack on the wall goes to the one marked LINE and not the one marked PHONE (that is for a handset)  Make sure that the POP the user is attempting to connect to is not busy. If it isn't then it is most likely a problem with the user's phone line. Make sure that the line they are tring to dial out on is not in use.  Sometimes this error occurs if the modem is a British Model and the user is not using the British to Irish adapter. Check if the modem is compatible with the Irish phone system by typing ati7 in HyperTerminal. If it says that the modem is British or another country then make sure that the user is using the correct converter.
• 677 A person answered instead of a modem.  Check the phone number the user is dialing is correct. Also ensure that they don't have "Use area code and dialing properties" ticked with the POP number. Check do they need to dial 9 for an outside line, if so are they dialing it? Check also for Telco services such as Call Waiting and Call Answering, if necessary get the user to contact their Telco for info on how to temporarily disable them. Get the user to dial the POP number from a phone handset and see what they get.  In 99% of cases this will cure it but if not :  Check that the POP the user is dialing is not down or busy.  If the POP is in working order get the user to dial a normal phone with their modem and see does it ring. If it rings then try this modem string :  ATZX0

  If the phone did not ring then it is likely that the modem is damaged in some way. Sometimes this error occurs if the modem is a British Model and the user is not using the British to Irish adapter. Check if the modem is compatible with the Irish phone system by typing ati7 in HyperTerminal. If it says that the modem is British or another country then make sure that the user is using the correct converter.

• 678 There was no answer.  First check that the POP the user is dialing is not down or busy.  Get the user to dial the POP number exactly as it is listed in DUN and see do they get an answer. If they do then chances are they are dialing extra number in "Dialing Properties". Take out any unnecessary settings from there.
• 679 The system could not detect the carrier.  The modem cannot detect the carrier signal.  This often happens if the modem is not connected properly to the phone socket. Make sure that the user has put the phone line in the correct socket in the back of the modem.  Make sure that the user can dial out using an ordinary phone handset on the same line. If they can't, get them to call their Telco. Also they can check the phone line quality by picking up an ordinary phone and pressing the number; 1. If they hear cracks and pops on the phone line get them to have the phone line checked by their Telco.
• 680 There was no dial tone.  The modem cannot detect the dial tone.  First check that there is a dial tone on the phone line by getting the user to see can they make a voice call over the same line. See do they hear a dial tone. If they are dialing through a PABX system try putting a few commas after the 9 or 0 that they use to get an outside line.  This often happens if the modem is not connected properly to the phone socket. Make sure that the user has put the phone line in the correct socket in the back of the modem.
• 681 The modem reported a general error.  This error is most likely caused by the user's modem.  First make sure that the modem is connected to the phone lines correctly and if it is an external modem make sure that the serial cable is connected to the right COM port and that the cable is not tangled.  Then check if the error occurs regularly or has only happened once.  If it only happened once then make sure the user's port speed is not set too high.  MAX Values:
  57600 for 56k modems
  38400 for 33.6k modems
  19200 for 14.4 modems

  If it happens regularly, check the port speed as above and then try these strings:
  AT&F1
  ATZ&B0&C1&D2

  If these have no effect then check that the modem is installed. Make sure that the driver installed matches the modem exactly. If not reinstall the modem (be careful of WinModems as they often have complicated installation procedures)

• 691 Access was denied because the user name and/or password was invalid on the domain.  In 99% of cases this will occur because the user has mistyped the username or the password wrong, no matter how hard they complain that they didn't. Get them to delete the username and the password and retype them. If necessary get them to practice typing the password in Notepad where it won't appear as asterisks and see do they get something different.  If that doesn't work, try deleting the *.pwl files
• 692 There was a hardware failure in the modem.  Close all programs, restart the computer and try again.  If the problem persists, then:  Try dialing using HyperTerminal, see can you get through to the username/password prompt.  If you can, then reinstall the modem. (Be careful with WinModems, make sure you use the disks provided by th manufacturer)
• 695 The state machines are not started.
• 696 The state machines are already started.
• 697 The response looping did not complete.
• 699 The modem response caused a buffer overflow.  Make sure the FIFO buffers are turned on if the user has a 16550 UART. If the buffers are on, try juggling with their settings until the error goes away.  Also try lowering their port speed to 9600 (set the FIFO buffers back to default) and work your way up the port speeds one by one until the error reoccurs. If the error occurs at 9600bps then the modem may be damaged, get the user to contact the manufacturer.
• 700 The expanded command in the device .INF file is too long.  The limit for commands in the script file is 256 characters. Break up the command into multiple commands.
• 701 The modem moved to a connection speed not supported by the COM driver.  Usually this problem can be solved by changing the maximum speed down to a lower setting until this error does not occur.  If that has no effect try adding &B1 to the init string.  If that does not solve the problem get the user to restrict their modem/TA to a lower BPS rate by using an init string supplied by the manufacturer of the modem.
• 703 The connection needs information from you, but the application does not allow user interaction.
• 704 The callback number is invalid.
• 705 The authorization state is invalid.
• 707 There was an error related to the X.25 protocol.
• 708 The account has expired.
• 709 There was an error changing the password on the domain. The password might have been too short or might have matched a previously used password.
• 710 Serial overrun errors were detected while communicating with the modem.  You probably will get this error in conjunction with frequent line drops with other error messages related to line drops.  Lower the port speed to one suitable for your modem, and try again.  Also try using &B0 in the modem string.
• 711 The Remote Access Service Manager could not start. Additional information is provided in the event log.
• 712 The two-way port is initializing. Wait a few seconds and redial.  Do exactly as it says, wait a while and reconnect.
• 713 No active ISDN lines are available.   Hang up all devices/handsets attached to your ISDN line and try again.  If this does not work then have the user contact their Telco and get the line checked
• 714 No ISDN channels are available to make the call.  Hang up all devices/handsets attached to your ISDN line and try again.  If this does not work then have the user contact their Telco and get the line checked
• 715 Too many errors occurred because of poor phone line quality.   The phone line quality is poor. Remove any splitters, shorten the cable and try again.  If the user is dialing out through a PBX system/switchboard test the line using a direct line if possible.  Make sure there are no appliances near the phone line which could cause interference and that the line is not coiled.  If none of these work try some strings such as:
  S10=50
  S10=100
  S10=100S25=200
  AT&F1X0S10=100S25=200S38=2
• 716 The remote access service IP configuration is unusable.
• 717 No IP addresses are available in the static pool of remote access service IP addresses.  This error only happens when the user dials into an NT RAS server.
• 718 The connection timed out waiting for a valid response from the remote computer.  A PPP conversation was started, but was terminated because the remote computer did not respond within an appropriate time.  This can be caused by poor line quality or by a problem at the server.
• 719 The connection was terminated by the remote computer.  This error should only occur due to a glitch on the ISP's end. Reconnecting should fix it. If it occurs regularly and there is no problem at the ISP, reinstall DUN/RAS.
• 720 The connection attempt failed because your computer and the remote computer could not agree on PPP control protocols.  First check that all their settings are correct.  Ensure that PPP is selected on the Server Types tab in their DUN connection.  If they are OK and you are still getting the error message, then reinstall DUN.
• 721 The remote computer is not responding.  This error should only occur due to a glitch on the ISP's end. Reconnecting should fix it. If it occurs regularly and there is no problem at the ISP, reinstall DUN/RAS.
• 722 Invalid data was received from the remote computer. This data was ignored.  A PPP packet was received that was not in a valid format.
• 723 The phone number, including prefix and suffix, is too long.  Check the phone number in Dial Up Networking and make sure it is correct. Make sure to check the area code, country code and outside line numbers if needed.
• 726 The IPX protocol cannot be used for dial-out on more than one modem at a time.   The user should probably not be using IPX to connect. Correct their settings accordingly.
• 728 The system cannot find an IP adapter.
• 729 SLIP cannot be used unless the IP protocol is installed.   Most ISPs don't use SLIP so the user should not be trying to use SLIP to connect. Change their settings to use PPP.  However, this error message may also indicate that TCP/IP is not installed. Make sure that it is.
• 731 The protocol is not configured.   Go to Control Panel/Network and make sure that TCP/IP is installed and configured properly.
• 732 Your computer and the remote computer could not agree on PPP control protocols.  The negotiation of PPP parameters did not succeed because the local and remote computers could not agree on a common set of parameters.
• 733 Your computer and the remote computer could not agree on PPP control protocols.
• 734 The PPP link control protocol was terminated.
• 735 The requested address was rejected by the server.  The client is configured to request a specific IP address.  Set it to DHCP
• 736 The remote computer terminated the control protocol.  This is probably due to a glitch on the ISP's end. The control protocol referred to in the error message is probably the Terminal Control Protocol (TCP) or the Link Control Protocol (LCP extensions).
• 737 Loopback detected.  The local and remote computers involved in the PPP conversation are the same computer. This usually means a device (for example, a modem) on the link is echoing characters back. Try resetting these devices.
• 738 The server did not assign an address.
• 739 The authentication protocol required by the remote server cannot use the stored password. Redial, entering the password explicitly.
• 740 An invalid dialing rule was detected.
• 741 The local computer does not support the required data encryption type.  You should not come across this error as most ISP's servers do not require encryption.
• 742 The remote computer does not support the required data encryption type.    You should not come across this error as most ISP's servers do not require encryption. So long as you send your passwords as clear text then this error won't occur.
• 743 The remote server requires data encryption.  You should not come across this error as most ISP's servers do not require encryption.
• 751 The callback number contains an invalid character. Only the following characters are allowed: 0 to 9, T, P, W, (,), -, @, and space.
• 752 A syntax error was encountered while processing a script.  You should not be using a script to connect. Turn off scripting and try again. If you need to log on using a terminal screen and have the script for that reason then have a look at the script. Check it out and see are there any typos in there. If necessary use this script, it is the most basic type of script you should need, just save it as a .SCP file and point your DUN connection to it.
• 753 The connection could not be disconnected because it was created by the multi-protocol router.
• 754 The system could not find the multi-link bundle.
• 755 The system cannot perform automated dial because this entry has a custom dialer specified.
• 756 This connection is already being dialed.
• 757 Remote access services could not be started automatically. Additional information is provided in the event log.
• 758 Internet connection sharing is already enabled on the connection.
• 760 An error occurred while routing capabilities were being enabled.
• 761 An error occurred while Internet connection sharing was being enabled for the connection.
• 763 Internet connection sharing cannot be enabled. There are two or more LAN connections in addition to the connection to be shared.
• 764 No smart card reader is installed.
• 765 Internet connection sharing cannot be enabled. A LAN connection is already configured with the IP address required for automatic IP addressing.
• 766 The system could not find any certificate.
• 767 Internet connection sharing cannot be enabled. The LAN connection selected on the private network has more than one IP address configured. Reconfigure the LAN connection with a single IP address before enabling Internet connection sharing.
• 768 The connection attempt failed because of failure to encrypt data.
• 769 The specified destination is not reachable.
• 770 The remote machine rejected the connection attempt.
• 771 The connection attempt failed because the network is busy.
• 772 The remote computer's network hardware is incompatible with the type of call requested.
• 773 The connection attempt failed because the destination number has changed.
• 774 The connection attempt failed because of a temporary failure. Try connecting again.
• 775 The call was blocked by the remote computer.
• 776 The call could not be connected because the destination has invoked the Do Not Disturb feature.
• 777 The connection attempt failed because the modem on the remote computer is out of order.
• 778 It was not possible to verify the identity of the server.
• 779 To dial out using this connection, you must use a smart card.
• 780 An attempted function is not valid for this connection.
• 781 The encryption attempt failed because no valid certificate was found
